Creating rough surfaces in ABAQUS
Creating rough surfaces in ABAQUS
(OP)
Hi,
I need to create rough surfaces in ABAQUS. The existing model is circular beams having perfect geometry, how can I incorporate disturbance/roughness to the existing surface? I have already tried *Imperfection approach but that's not giving me enough roughness.

Sorry, just trying to understand your problem
RE: Creating rough surfaces in ABAQUS
If I use the *Imperfect approach, I get unevenness as in large wavy shape, whereas I need the disturbance to be small wave like, discrete.

RE: Creating rough surfaces in ABAQUS
Why is it important? How does surface finish affect the response? How is your model behaving unexpectedly without rough surfaces? Is it for contact? If so you can adjust the tangential interaction properties to replicate rough surface interaction without explicitly modelling the rough surface finish.
RE: Creating rough surfaces in ABAQUS
Is there a method to correlate rough surface properties (i.e. Ra or Rz) to tangential interaction properties??
RE: Creating rough surfaces in ABAQUS
I don't think you can make a reliable correlation without testing, but you should check the literature.
